英文摘要:

      Objective To study the effects of Chinese leek seed meal extract on the physicochemical properties of Chinese leek seed oil microcapsule. Methods The effects of Chinese leek meal extract on the microstructure, embedding rate, storage stability, solubility and fluidity of Chinese leek seed oil microcapsules were investigated by scanning electron microscopy, solubility and fluidity experiment, thermogravimetry analysis and Fourier transform infrared spectroscopy, the release of leek seed oil in digestive tract was studied by simulated digestion experiment in vitro. Results The microcapsules with Chinese leek meal extract had regular shape and smooth and compact surface; Chinese leek meal extract could increase the embedding rate of microcapsules to 93.272%, effectively inhibiting the oxidation of microcapsules, improving the solubility and mobility of microcapsules; with the increase of temperature, the maximum weight loss rate of microcapsules supplemented with Chinese leek meal extract had a certain protective effect on microcapsules. The infrared results showed that the microencapsulation effect and the embedding was successful. In simulated digestion experiment in vitro, the microcapsules added with the extract of leek meal could release Chinese leek seed oil more effectively and improved the bioavailability of Chinese leek seed oil in human body. Conclusion The study provides theoretical references for the development of Chinese leek seed oil microcapsules products and the establishment of application system.
